Solved android android-activity fullscreen android-fullscreen

How to set full screen mode for activity in Android? I am using the following code to set full screen but it generates an error:

Exception:

android.util.AndroidRuntimeException: 
    requestFeature() must be called before adding content.

Code:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,        
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);

Hello all , Problem solved when I write code before setContentView(R.layout.main); . Thank you! All for your answers. – Beaty 12/9, 2012 at 13:28

please check the code

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.main);
}

and note it is set before setting the content view

You might still see another error specifically with Amazon devices. You need to call requestWindowFeature before super.onCreate(). See the following answer: https://mcmap.net/q/513380/-how-to-set-activity-to-fullscreen-mode-in-android-duplicate – Soembawa 21/2, 2015 at 22:32

is there any xml equivalent for this ? – Gloze 27/1, 2016 at 18:53

try this in AndroidManifest:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
</activity>

This code I used in MAIN activity. Activity name already declared in AndroidManifest. – Beaty 12/9, 2012 at 13:8

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                        WindowManager.LayoutParams.FLAG_FULLSCREEN);

No Mayank this code also not work for me – Beaty 12/9, 2012 at 13:16

Code: public class Draw extends Activity { SignatureView sv; RelativeLayout rLayout1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); rLayout1 = (RelativeLayout) findViewById(R.id.relativeLayout1); // Set full screen view getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); requestWindowFeature(Window.FEATURE_NO_TITLE); sv = new SignatureView(this, null); rLayout1.addView(sv); sv.requestFocus(); } } This is my code – Beaty 12/9, 2012 at 13:17

@RanjitChandel setcontent view should come afterwards check my code below – Addington 12/9, 2012 at 13:19

put requestWindowFeature first in your code....like this...

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
